Hi,
at the end this worked for me:
:; cat<<EOF|lxd init --preseed
cluster:
enabled: true
server_name: ${HOSTNAME%%.*}
server_address: ${HOSTNAME%%.*}:8443
cluster_address: cluster:8443
cluster_certificate: "$(sed ':a;N;$!ba;s/\n/\n\n/g' /tmp/cluster.crt)
"
cluster_password: “password"
member_config:
- entity: storage-pool
name: your-storage-pool-name
key: source
value: yourzfspool/yourzfsfs
EOF
the trick is that you have to first migrate or delete all the existing
containers on the joining node and destroy the storage pool if it has the same
name as the cluster pool. New node can only join the cluster completely empty,
I don’t know why I was somehow expecting that the existing containers will be
merged with the ones in the cluster. It is a nice feature request though ;)
